Arrived in homeowner greeted me at the front door I asked him what was going on. He told me that the whole system shuts off, but the fan motor will never shut off. I confirmed that the outside unit was off I pulled the thermostat off. We do make sure it wasn’t a bad thermostat. I went inside a/h and made sure the board wasn’t bad This system Has a Bad ecm motor The surge protector inside the air handler as faulty as well I have office checked warranty and this is out of warranty. I use the X 13 truck motors on my truck. I installed and tested the system back up and running at this time Thank you For being part of the Total Air family Dan E
